Constructor Detail

FS_Win32

public FS_Win32()

Constructor

FS_Win32

protected FS_Win32(FS src)

Constructor

Parameters:

src - instance whose attributes to copy

Method Detail

newInstance

public FS newInstance()

Create a new instance of the same type of FS.

Specified by:

newInstance in class FS

Returns:

a new instance of the same type of FS.

supportsExecute

public boolean supportsExecute()

Does this operating system and JRE support the execute flag on files?

Specified by:

supportsExecute in class FS

Returns:

true if this implementation can provide reasonably accurate executable bit information; false otherwise.

canExecute

public boolean canExecute(java.io.File f)

Determine if the file is executable (or not).

Not all platforms and JREs support executable flags on files. If the feature is unsupported this method will always return false.

If the platform supports symbolic links and f is a symbolic link this method returns false, rather than the state of the executable flags on the target file.

Specified by:

canExecute in class FS

Parameters:

f - abstract path to test.

Returns:

true if the file is believed to be executable by the user.

setExecute

public boolean setExecute(java.io.File f,
                          boolean canExec)

Set a file to be executable by the user.

Not all platforms and JREs support executable flags on files. If the feature is unsupported this method will always return false and no changes will be made to the file specified.

Specified by:

setExecute in class FS

Parameters:

f - path to modify the executable status of.

canExec - true to enable execution; false to disable it.

Returns:

true if the change succeeded; false otherwise.

isCaseSensitive

public boolean isCaseSensitive()

Is this file system case sensitive

Specified by:

isCaseSensitive in class FS

Returns:

true if this implementation is case sensitive

retryFailedLockFileCommit

public boolean retryFailedLockFileCommit()

Does this file system have problems with atomic renames?

Specified by:

retryFailedLockFileCommit in class FS

Returns:

true if the caller should retry a failed rename of a lock file.

discoverGitExe

protected java.io.File discoverGitExe()

Discover the path to the Git executable.

Specified by:

discoverGitExe in class FS

Returns:

the path to the Git executable or null if it cannot be determined.

userHomeImpl

protected java.io.File userHomeImpl()

Determine the user's home directory (location where preferences are).

Overrides:

userHomeImpl in class FS

Returns:

the user's home directory; null if the user does not have one.

runInShell

public java.lang.ProcessBuilder runInShell(java.lang.String cmd,
                                           java.lang.String[] args)

Initialize a ProcessBuilder to run a command using the system shell.

Specified by:

runInShell in class FS

Parameters:

cmd - command to execute. This string should originate from the end-user, and thus is platform specific.

args - arguments to pass to command. These should be protected from shell evaluation.

Returns:

a partially completed process builder. Caller should finish populating directory, environment, and then start the process.

supportsSymlinks

public boolean supportsSymlinks()

Does this operating system and JRE supports symbolic links. The capability to handle symbolic links is detected at runtime.

Overrides:

supportsSymlinks in class FS

Returns:

true if symbolic links may be used

detectSymlinkSupport

private void detectSymlinkSupport()

getAttributes

public FS.Attributes getAttributes(java.io.File path)

Get the file attributes we care for.

Overrides:

getAttributes in class FS

Parameters:

path - a File object.

Returns:

the file attributes we care for.
